The purpose of this review paper is firstly to give an overview of aerodynamic performance of HAWT and description of recent develo pments and current status of the drag - reduction research. The wind energy is deemed as one of the most durable energetic variants of the future because the wind resources are immense. Therefore research in this field must be continuous and interdisciplinar y. The objective of these investigations is to improve the wind turbines aerodynamic performance and increase their operational range by inducing complete or partial flow reattachment. Through CFD simulations for a horizontal axis wind turbine, this study is trying to analyse the flow field around the wind turbine blade. Current efforts focus on increasing their aerodynamic efficiency and operational range through passive flow control techniques.
